Scrap Preheating

Scrap preheating is a technology that can reduce the power consumption of EAFs through from using the waste heat of the furnace to preheat the scrap charge. Scrap preheating is performed either in the scrap charging baskets, in a charging shaft (shaft furnace) added to the EAF, or in a specially designed scrap conveying system allowing continuous charging during the melting process. Shaft furnace and tunnel furnace systems are more modern and efficient preheating.
